There is a chamber at NASA’s Johnson Space Center in Houston that is, in its own way, one of the most extraordinary rooms on Earth. Chamber A is one of the largest thermal vacuum facilities in the world, a vast steel vessel that can recreate the airless, temperature swinging brutality of space without leaving the […]

When astronomers discovered the first planet outside our solar system, it was orbiting a pulsar, one of the most extreme, radiation-blasted environments imaginable. Not exactly the kind of place you’d expect to find a planet, let alone a representative one. The first confirmed exoplanet was an oddity, a product of the fact that pulsar timing […]

Our solar system has two ice giants, Uranus and Neptune, but there may have been a third. According to a new study published in the journal Icarus, this extra world might have triggered a violent planetary shuffling billions of years ago that could have disrupted some of Jupiter’s and Uranus’s moons and possibly led to […]

An international team led by astronomers at the University of Sydney has uncovered the clearest evidence yet for the origin of an unusual class of cosmic signals. In doing so, they have identified a rare stellar system that is providing scientists with a natural laboratory to study extreme physics.

Life exists because elements combine to form complex organic molecules. Astrochemistry studies this process, trying to understand how nature creates carbon-based molecules critical for life. One source for these types of molecules is the outflows emitted by protostars.
